摘　　要：目的建立环境扫描电镜(ESEM)法推断毛发致伤物种类的新方法。方法应用ESEM观察分析不同锐器、钝器及致伤方式形成的毛发机械性损伤的微观形态特征。结果毛发锐器、钝器损伤的表面微观特征存在显著差异,同种类型致伤工具,其锋利程度、作用方式不同时,其损伤特征也明显不同。结论ESEM法能够真实、自然反映毛发机械性损伤表面微观特征,可应用于推断毛发致伤物种类。Objective To establish a new method for estimating the type of the instrument which caused the trauma of the hair using Environmental Scanning Electron Microscope （ESEM）. Method ESEM was used to image and analyze the morphological characterizations of the physical damaged hairs, which caused by different sharp or blunt instruments and with different manners. Results There was an obvious relationship between the morphological characterizations of breaking hair and the type of the tools, the sharp degree of the tools, and the rnarlner of the damage. Conclusion ESEM allows imaging and analyzing the morphological characterizations of the breaking hairs in their real and natural state, so it offers a new method for estimation of the type of the instrument which caused the trauma of the hair.
